Can you explain your idean in more detail?
"They are not limited in speed by the capacitance between n and p region anymore, but by the time the electrons need to drift across the undoped region." This is not true. It depends on the thickness of the undoped zone and the area of the detector. Usually you'd want to maximise the area and thickness so that the drift time and the capacitances has about the same limitation in speed.
"A PIN diode exhibits an increase in its electrical conductivity as a function of the intensity, wavelength, and modulation rate of the incident radiation." Well usually you'd use the pin diode in reverse BIAS and it is not so much the conductivity change as the current generation that is the physics behind it. But I guess it is almost the same thing.
"PIN diodes act as near perfect resistors at RF and microwave frequencies. The resistivity is dependent on the DC current applied to the diode." A PIN diode acts as a diode not as a resistor. A pin diode has an internal capacitance thus not a perfect resistor. The capacitance is dependant on the DC voltage applied to the diode.
Yes, this page is better than nothing but it needs some work. I'm not the one to do it though at the moment, I'm not familiar with PIN diodes.
I just finished my undergraduate thesis on studying PiN diodes when I get some time I am going to add corrections, in 8-10 weeks you can looked for my at my thesis, at the University of Central Florida "Modeling and Analysis of PiN Power Diodes in Series" —Preceding unsigned comment added by 188.8.131.52 (talk) 19:19, 2 April 2008 (UTC)
Possible resource worth reviewing
Anybody with the expertise (Atlant, maybe?) willing to take a crack at parsing this  and using the information to help fill in the technical details in the article. I tried to clean up the operation section, but it's still sketchy. I don't find the holey bucket analogy particularly insightful. If anything, I think it makes things more confusing. --W0lfie (talk) 15:53, 7 April 2008 (UTC)
Possible application to be included
gives a use of pin diodes in silicon lasers.
i'm not sure if this is relevant or too detailed for this section and if it is relevant i thus far lack the technical skill to summarise it.
nice piece of work though
